MAP sensor accuracy test 2 - Ford Focus 1.6 16V Zetec SE
6Just a follow up to the previous video - this time I'm using Forscan Lite, so the readings update a bit faster (though the refresh rate is still much lower than what you can get when using the graph mode in Forscan Lite - should've used that) and I also included various other readings relevant to my attempts at solving the issues I'm having.
Most importantly, I've included the BARO reading, since with the last video, I totally forgot the fact that MAP sensor reads absolute pressure, while the vacuum gauge reads relative vacuum, so it's important to know how the two relate at the time of the test.
For the record, the official atmospheric pressure at the time of the test was 101.7 kPa according to the local weather station - that's adjusted for sea level, so if I'm not mistaken, that means the MAP sensor is actually reading around 1 kPa lower pressure than it should at my altitude (220 meters above sea level) even when it comes to atmospheric pressure. But I'm not sure what the supposed accuracy of the MAP sensor is according to specs, it might very well still be within tolerance.
